Description

Technical Field

[0001] This utility model relates to the technical field of lighter assembly equipment, and in particular to a gasket feeding device for a lighter oil tank. Background Technology

[0002] In the lighter assembly line, before inserting the electronic igniter into the oil tank, a shim needs to be placed in the mounting slot of the electronic igniter in the oil tank. The shim acts as a buffer and shock absorber to reduce friction and pressure between the electronic igniter and the oil tank. Existing assembly equipment usually uses grippers to place the shim into the mounting slot of the oil tank, and then a push rod is inserted to force the shim in the mounting slot into the positioning slot. Due to the expansion and descrambling characteristics of the grippers, it is difficult for them to reach into the mounting slot, making it impossible to accurately place the shim at the entrance of the positioning slot. The shim is not aligned, so it cannot be installed in place, which in turn leads to misalignment in the subsequent assembly of the igniter and the flip-flop. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Please see Figures 1 to 5 A gasket feeding device for a lighter fluid reservoir includes a gasket vibrating feeding plate 1, a reservoir fixture 2, and a negative pressure generator. A multi-axis moving assembly 3 is provided between the reservoir fixture 2 and the gasket vibrating feeding plate 1. A gasket picking and placing mechanism 4 is mounted on the multi-axis moving assembly 3. The gasket picking and placing mechanism 4 includes a gasket picking component 41, which has a negative pressure channel 42 connected to the negative pressure generator. The lower end face of the gasket picking component 41 has a negative pressure port 43 for absorbing the gaskets 7 fed from the gasket vibrating feeding plate 1 and placing them in the fluid reservoir 5. Through the suction-type gasket picking component 41, the negative pressure generator controls the negative pressure suction; breaking the vacuum allows the material to be placed. The gasket picking component 41 does not expand or contract, thus it can easily extend into the fluid reservoir 5 to accurately place the gaskets, avoiding misalignment problems during subsequent electronic installation.

The protruding design of the guide rod realizes the pre-positioning function, and completes the hole alignment before adsorption, thereby improving the positioning accuracy; the coaxial structure ensures that the mechanical guidance and the negative pressure adsorption action line coincide, eliminating torque interference; the layout of the guide rod circumferentially surrounding the negative pressure ports 43 forms a synergistic action mode of central positioning + peripheral adsorption.

[0028] Please see Figures 1 to 2 , Figure 4 Preferably, the gasket picking and placing mechanism 4 further includes a floating connector mounted on the gasket moving frame 31, and the floating connector is provided between the gasket picking component 41 and the gasket moving frame 31; the floating connector includes a floating cylinder 44 and a floating joint 45, the floating joint 45 is connected to the push rod of the floating cylinder 44, the lower end of the floating joint 45 is connected to a gasket pressing slide plate 46, the lower side of the gasket moving frame 31 is provided with a guide mounting plate 47, the guide mounting plate 47 is provided with a guide sleeve guide hole, the top of the gasket picking guide sleeve 411 passes through the guide sleeve guide hole, and the upper end of the gasket picking guide sleeve 411 can abut against the lower end of the gasket pressing slide plate 46; the guide sleeve guide hole is provided with an axial displacement limiting component to limit the axial travel of the gasket picking guide sleeve 411. The floating connection design absorbs mechanical positioning errors and prevents damage to the gasket guide rod 412 from hard contact with the oil groove 5 caused by rigid contact; the axial limiting mechanism controls the pressing depth and prevents the gasket picking guide sleeve 411 from falling off the mounting bracket.

[0029] Please see Figures 1 to 3 , Figure 5 Preferably, the outlet end of the vibrating feeder 1 is connected to a gasket cutting mechanism 6. The gasket cutting mechanism 6 includes a cutting block 61 and a gasket pushing assembly.

The gasket receiving groove 611 is connected to the outlet of the vibrating feeder 1, and the gasket pushing assembly is connected to the gasket receiving groove 611 of the cutting block 61. The cutting mechanism achieves precise connection between continuous feeding and intermittent picking by the vibrating feeder; the gasket receiving groove 611 serves as a buffer station to ensure that the picking mechanism picks up a single gasket each time; the gasket pushing assembly and the cutting block 61 cooperate to form a controllable discharge mechanism to prevent gaskets from accumulating and jamming.

[0030] Please see Figures 1 to 3 , Figure 5Preferably, the gasket pushing assembly includes a gasket push rod 62 and a push rod drive component 63. The push rod drive component 63 is installed on the lower side of the cutting block 61. The lower side of the gasket receiving groove 611 is provided with a push rod clearance hole. The gasket push rod 62 is installed on the push rod drive component 63, and the gasket push rod 62 can pass through the push rod clearance hole. The push rod clearance hole design realizes the timing coordination of the ejection action and the material picking action; the double push rod structure is adapted to the dual-station design, improving the overall operating efficiency of the equipment. Preferably, the push rod drive component 63 is a cylinder.

[0031] Please see Figures 1 to 3 , Figure 5 Preferably, the gasket groove 611 is fitted with a gasket fiber optic detection sensor 64; two gasket grooves 611 are arranged side by side, and correspondingly two gasket top rods 62 are provided; two gasket picking guide sleeves 411 are arranged side by side. The fiber optic sensor monitors the feeding status in real time to ensure the effectiveness of the picking action; the dual-station parallel processing design increases equipment capacity by 100% and optimizes production efficiency; the redundant detection mechanism prevents empty grabbing and reduces the risk of equipment failure and downtime.

[0032] The working principle of this utility model is as follows:

[0033] The shim vibrating feeding tray 1 is conveyed via a track with a linear vibrator to the shim receiving slot 611, which is connected to the cutting block 61 of the shim cutting mechanism 6. (After a shim enters the shim receiving slot 611, it will block the entry of subsequent shims until it is removed.) The rotary cam linkage mechanism drives the shim moving frame 31 to move to the station on the shim receiving slot 611, so that the shim picking component 41 approaches the shim on the shim receiving slot 611. Then, the push rod drive component 63 of the shim pushing assembly drives the shim push rod 62 to push upward, so as to push the shim in the shim receiving slot 611 upward, so that the shim... The guide rod 412 is inserted into the positioning hole of the gasket. The negative pressure generator works to generate negative pressure at the negative pressure port 43 to suck up the gasket. Then, the rotary cam linkage mechanism drives the gasket picking component 41 to move and extend into the positioning groove of the oil tank 5, so that the gasket guide rod 412 is coaxial with the positioning groove. The cylinder of the floating connector pushes the gasket down into the slide plate 46, which in turn drives the gasket picking guide sleeve 411 to move down and press the gasket into the positioning groove of the oil tank 5 (the positioning hole of the gasket and the gasket guide rod 412 are clearance fit, so it will not get stuck on the gasket guide rod 412). Then, it resets and picks up the gasket again, and so on in a cycle.
